Oh I never would scrub any optical surface, I meant it in a generic
context :) ! Am I safe in assuming that the mirror is removed while
cleaning? Also is the mirror aluminized on the front or rear surface (I
assume its rear sufrace silvered)? That's something I've never actually
looked at but I assume it could affect the cleaning process somewhat.
By the way there is a lot of talk about Q-tips. What are they?
Special optical cleaners or the preverbial cotton bud?
All the best,
Gareth.

I wouldn't suggest ever 'scrubbing' on a mirror. In my experience, even
Windex on a Q-tip can cause scratches. The mirror coating is *that*
delicate! If you're going to clean a mirror, flood it with fluid (I use 91%
isopropanol alcohol) using a wadded up piece of plain white toilet tissue.
Then using another wadded up piece of dry toilet tissue, gently (*gently!*)
swab up the liquid.
This will leave a lot of little tissue fibres in the mirror area. Gently
(*gently!*) blow these out with short puffs of canned air or from a squeeze
blower. That's it. No scrubbing, contact with Q-tip, or anything else. Q-tip
cotton fibres can be quite abrasive, and this will wear the mirror coating
right through in a couple swipes. Ask me how I know... :-(
Remember, 'do-it-yourself camera' fixing is a lot like 'do it yourself
lawyering' or 'do it yourself doctoring', you want to be sure you don't have
a fool for a client. I would start on something a lot less desirable than
any OM body...
